Not to worry. Undoubtedly somebody over there will decide that the jelly, tentacles, venom, whatever, of the giant jellyfish is either a delicacy or an aphrodisiac, and they will be hunted relentlessly, the authorities will become alarmed and try to manage the resource, and then they will be poached into near extinction as they have with such silly things as horns from the black rhinoceros. Too bad we haven't found a good use for the flesh of idiots.
